Is the "Straight Lock Grip" a remedy for those former NG swingers who decided to shift to Simple Swing?

I've tried Natural Golf before and Natural golfers hit the ball with their right hand dominating the swing. Thus, when I am practicing my SS, the right/trail hand sometimes creeps in and dominate the swing.

You said however that the "Straight Lock Grip" tries to work around the bad habits/faults picked up from other golf swings. Can you elaborate on this?
